Crank window part

A handy person from Cincinnati, Ohio says:
Hello! My window no longer cranks open, the handle just spins. I was hoping to see which part or assembly is needed. Thanks!

It sounds like your operator gears are stripped out, which will necessitate total replacement of the operator in question. We can help, but I will need to see a clear photo of it removed from the window entirely.

A handy person from Cincinnati, Ohio says:
Thanks for the reply. I unscrewed the handle with a small flat head screw driver. The spine does keep spinning, so something inside isn't working properly.

Any idea how the plate / cover comes off to expose the mechanism?

I can't seem to force it off. Thanks!

Yep, the gears are definitely stripped. You will need an all new operator.

Odds are the cover cannot be removed in your case. Older operators like this were designed so that the "cover" is permanently affixed to the base. That wouldn't help, anyway; we need to see the entire mechanism out of the window in order to match it up.

Here's a photo I snapped today to try to disassemble. Unfortunately it'll probably have to wait until Spring since today maybe be the last nice day weather-wise here. Hopefully I can at least get the parts needed.

This photo is perfect, honestly. There are a few key details on display here that tell me exactly what I need. This operator appears to be an older version of our 39-221B . Coincidentally, this newer version's cover and handle are sold separately under our 39-451 kit and are fully detachable.

I'm pretty confident these are the parts you want, but you should look over them carefully just to see for yourself. Let me know if you had any questions or doubts.

Thank you so much for the help! Just ordered the parts.
